What is fault throw switch. How it oprtate. What is subsequent effect to system?

A fault throw switch is a protective device used in electrical systems to isolate faulty sections by diverting fault currents away from sensitive equipment. It operates by detecting a fault condition and mechanically switching the circuit to a predetermined safe state, often redirecting the current through a bypass or alternate route. The subsequent effect on the system includes improved reliability and protection for equipment, minimizing downtime and potential damage by quickly isolating problematic areas. This allows the rest of the system to continue operating normally while repairs are made.
